Abstract: A B S T R A C T     This invention is for a process for the recovery of base metals such as copper, nickel, cobalt and molybdenum that are present in manganese containing ores and  in which the ore is brought into contact with cuprous ions in a vessel thus reducing the oxides in the ore and enabling the metal values to be solubilized.  At the same time regeneration of cuprous ions is accomplished by carbon monoxide reducing gas which is introduced to the reacting mixture under pressure.

Abstract: OXYGEN BLEACHING OF PULP IN PRESENCE      OF HIGH-SILICA PROTECTOR     Abstract of the Disclosure The disclosed colloidal high silica protector materials protect carbohydrates in chemical cellulosic pulps from oxidative attack during oxygen bleaching in alkaline media at elevated temperatures and superatmospheric pressure.  These protector materials are useful in processes which produce high yields of semi-bleached and fully bleached pulps.  The preferred bleach sequences for fully bleached pulps begin with an O stage, e.g. O-D-H, O-D, ODED, and OH, as well as OCEDED, OCED, OCDEDED, etc. A fully bleached kraft pulp of this invention compares favorably in virtually all respects to a fully bleached kraft pulp obtained by the environmentally objectionable chlorine bleach sequences. The preferred protectors are high silica water glass compositions wherein the silica/sodium oxide ratio is at least 1.6, preferably at least about 2.0 on a weight/weight basis.

Abstract: MEANS FOR SENSING CHANGE IN THE AMOUNT OF FLUENT MATERIAL IN A RESERVOIR     ABSTRACT OF THE DISCLOSURE         A fluid level sensor comprising a novel electronic circuit which monitors change in the fluid level in a reservoir through a conductive probe disposed therein.  The probe and a capacitor are electrically connected in a circuit which is intermittently energized to create an electrical transient therein The transient is monitored, and a warning is given when the transient indicates that the probe is not in contact with the fluid in the reservoir.  Two species of the invention are disclose as applied to a vehicle hydraulic brake system having a dual reservoir type master brake cylinder with a probe for each reservoir.  In one species, only a single capacitor is required since the electronic circuit electrically connects each probe with the capacitor sequentially by means of time multiplexing. in the other species, a capacitor is required for each probe and the transients in each capacitor/probe circuit are red to a logic circuit which determines if any of the probes is out of contact with the fluid in the reservoir.  The electronic circuit is especially adapted for fabrication as an integrated circuit chip using C-Mos technology.  With such a circuit chip a minimum number of terminals are required to connect external components to the chip for performing the fluid level sensing function.

Abstract: ABSTRACT      It is known to prepare silica particles by the known sol-gel method.  However silica particles prepared by the known method have a lower bulk crush strength and a lower water resistivity than desired. These properties of silica particles may be improved by the present invention which provides a process for the preparation of globular silica particles having a water resistivity of at least 80% and a bulk crushing strength of at least 12 kg/cm2, which process comprises the following successive steps: a) preparing a silica hydrosol by mixing an aqueous solution of an alkalimetal silicate wit  an aqueous solution of an acid, b) converting the hydrosol into droplet form, c) gelling the droplets in a liquid which is not miscible with water, d) removing at least 25% of the amount of water present in the hydrogel particles by evaporation, e) decreasing the alkali-metal content of the hydrogel particles in an aqueous medium to less than 1% w calculated on dry material, and f) drying and calcining the globular silica particles.  The so prepared silica particles are useful as catalysts, catalyst carriers, adsorbants, drying agents and ion exchangers.

Abstract: Abstract of the Disclosure In a rammer a piston housed in a combustion cylinder strikes with its impact surface the adapted impact surface of a striker. When the impact surfaces are spherical or flattened the piston may strike against the cylinder wall, as a result of which the cylinder surfaces and the piston surfaces wear off strongly.          In accordance with the invention the impact surfaces have a tangential cone having an obtuse apex so that on the one hand a sufficient centering of the piston with respect to the striker is obtained and on the other hand the risk of cracking in piston and striker is prevented.

Abstract: ABSTRACT:        The invention relates to a flash array provid-ed with a number of high voltage combustion flash lamps which are arranged in the reflector of an electrically conducting material. This reflector has been provided with holes; when a lamp is flashed a radiation-sensi-tive switching contact is affected via such a hole.        According to the invention the radiation-sen-sitive contacts are break contacts and these break con-tacts and the reflectors are connected to one another via a low-ohmic connection and whereby further a lamp, whose turn has not yet come, is short circuited. These measures result in the fact that the chance for pre-mature ignition of a lamp is extremely small.        Fig. 1.

Abstract: ABSTRACT OF THE DISCLOSURE           A three-phase wattmeter for measuring watts (or VAR's) in a three-phase power system.  The wattmeter employs a single multiplier to multiply a signal proportional to voltage by a signal proportional to current.  A switching circuit, in series with the inputs to the multiplier, operates so as to cause the signals applied to one input of the multiplier to oscillate between one of several voltage representative signals.  Similarly, the switching circuit causes the signals applied to the other input of the multiplier to oscillate between one of several current representative signals.  The oscillations between the signals are made in unison so that the multiplier is always multiplying a given voltage representative signal by a given current representative signal.  The output of the multiplier then indicates the average of these products. (i.e. the average power in the three-phase system).
